Semi coke, also called semi-coked coal or semi-coke, is a high-quality carbonaceous material produced by the pyrolysis and carbonization of low-rank or bituminous coal at high temperatures. It features a porous structure, high fixed carbon content, and low ash and sulfur levels.
Widely used in metallurgy, chemical, and energy industries, semi coke serves as an efficient fuel and reducing agent. Thanks to its excellent combustion performance and strong reduction ability, it is ideal for steelmaking, cast iron production, and other metallurgical processes.
Available in various sizes and specifications to meet diverse industrial needs, Hongshun's semi coke guarantees stable quality, reliable supply, and competitive pricing.
Semi Coke Key Features:
High Fixed Carbon: Typically >83%
Low Sulfur & Phosphorus: Ideal for high-purity processes
Low Reactivity & Strong Lump Structure: Stable during smelting
Low Ash & Moisture Content
Applications of Semi Coke
1. Ferroalloy Industry
Semi coke is widely used as a reductant in the production of ferroalloys such as ferrosilicon, silicon metal, ferrochrome, and ferromanganese. Its low sulfur and phosphorus content helps improve the purity and performance of the final alloys.
2. Calcium Carbide Production
Semi coke is a preferred fuel and carbon source in calcium carbide furnaces, where its high fixed carbon and low volatile content ensure stable furnace operation and improved efficiency.
3. Chemical Industry
Used in gasification and carbon-based synthesis, semi coke serves as a key feedstock for producing chemical products such as synthetic ammonia and methanol.
4. Metallurgical Coke Substitute
Semi coke can be used as a cost-effective and eco-friendly alternative to traditional metallurgical coke in various high-temperature industrial processes, especially in small and medium-sized electric arc furnaces.
5. Foundry and Smelting
In foundry applications, semi coke can be used as a carburizer or support fuel due to its high carbon content and low impurities, which contribute to better melt quality.
6. Power Generation and Heating
In some cases, semi coke is used as a solid fuel in industrial boilers and thermal power plants, offering lower emissions compared to standard coal.
